Growth of transgenic and WT seedlings under salt stress. Five-day-old seedlings grown on MS plates were transferred to MS plates containing 0, 50, 75, and 100 mM NaCl. a The seedlings were photographed after 2 weeks of growth. The growth was assessed based on fresh weight (b), root length (c), and number of lateral roots (d). Data are presented as mean ± SE of 12 replicates, where the different letters above the columns indicate statistically significant differences at a p < 0.05 level between the experimental cohorts. SpSOS1, SpSOS1-overexpressing plants; SpAHA1, SpAHA1-overexpressing plants; SpSOS1-SpAHA1, SpSOS1 and SpAHA1 co-expressing plants; WT, wild-type plants
